1 Claim.

My invention relates to improvements in chairs of the stool type for use more particularly in kitchens.

My invention has for its principal object the I provision of a chair of the type above indicated which is adjustable within a wide range of variations to diiferent heights, is easy to adjust, strong and durable, safe and inexpensive to manufacture.

To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawings, set forth in detail in the succeeding description, and defined in the claim appended hereto.

In said drawings:

Figure 1 is a view in front elevation of a chair embodying my improvements,

Figure 2 is a view in top plan,

Figure 3 is a View in vertical section taken on the line 3-3 of Figure 1,

Figure 4 is a view in horizontal section taken on the line 44 of Figure 3 looking in the direction indicated by the arrows,

Figure 5 is a view in perspective of the seat post, and

Figure 6 is a detailed view in horizontal section taken on the line 66 of Figure 3 looking downwardly and drawn to an enlarged scale.

Referring to the drawings by numerals, the chair of my invention comprises a stool-like base i including a top 2, preferably rectangular, corner legs 3, preferably diverging downwardly, and a horizontal spider-like support 4 intermediate the top 2 and the lower ends of the legs 3 secured at its outer ends to cross bars 5 suitably secured to said legs 3. The top 2 and legs 3 are preferably formed of wood and the support 4 and cross bars 5 of metal. In the vertical center of the described base I is a tubular guide 6 vertically disposed and having its opposite ends suitably secured in the top 2 and support 4 with its upper end opening onto the top 2 of the base I. Slidably mounted in the guide 6 is a cylindrical seat post I having an enlarged disk-like head 8 upon which there is suitably secured, concentrically thereof, a circular seat 9 provided with a transversely arcuate back rest It secured to the edge of the seat 9, as by screws H. The post I may be formed of wood or metal, as desired, the seat 9 being preferably of wood, and the back rest ID of sheet metal. The seat 9 is adapted to be adjusted to different levels by adjustment of the seat post I in the guide 6 into different set positions. For this purpose, the seat post I is provided with lon- 1938, Serial No. 196,555

gitudinally spaced diametrical apertures 12 adapted to register in different set positions of the seat post I with an aperture [3 provided in the guide 6 at the front thereof and adjacent the top 2. The seat post I is adapted to be locked to guide 6 in the different set positions thereof by means of a Y-shaped locking member l4 having a short arm I5 adapted to be inserted through the aperture l3 and into a registering aperture I2, a long arm l6 adapted to extend transversely along side the guide 6, and a stem ll terminating in a right angled finger grip part l8 for manipulation of said member M to insert the short arm l5 into said apertures l3 and i2. The member [4 is tensioned against manipulation to withdraw the short arm I5 from said apertures by means of a tension spring l9 secured at one end, as at 20, to the extremity of the long arm I6 and having its opposite end secured to an eye-screw 2| threaded into the underside of the top 2. As will be clear, in any set position of the seat post 1, said post is locked so that the chair may be lifted by the seat 9. Upon manipulation of the member 14 to withdraw the short arm 15 from one of the apertures 12 the post-1 and seat 9 will gravitate into a lowermost position in which the head 8 limits such gravitational movement. To prevent the head 8 under such conditions from banging against the top 2 a rubber bumper 22 is provided on said top for engagement with said head 8.

From the foregoing it will be seen that in the chair of my invention the seat may be readily adjusted vertically as desired and securely locked in adjusted position and against turning, that the device has few parts and cannot get out of order.

My invention will, it is believed, be readily understood from the foregoing without further explanation.

Manifestly the invention, as disclosed, is susceptible of modification without departing from the inventive concept and right is herein reserved to such modifications as fall within the scope of the subjoined claim.

What I claim is:

A chair of the class described comprising a stool-like base having a top, legs supporting the top, and a spider-like support extending horizontally between said legs intermediate the ends thereof, a tubular guide disposed in the vertical center of the base and having its opposite ends secured in said top and support, respectively, a post vertically slidable in said guide to different positions, and means to lock the post to the guide in the different positions thereof comprising 'a forked locking member having a locking leg means swingably securing the member to said top comprising a coil spring connected to said other leg and top, respectively, and tensioning the said member against removal from said aperture and bores. 7
